Type, Sastra placida. 



The smaller head, much shorter and transverse face, together 

 with the much more pubescent upper surface of the body, will 

 sufficiently distinguish Sastra from Momcea. 



Sastra placida. 



S. elongata, modice convexa, sordide flava, nitida ; abdomine anten- 

 nisque fuscis, bis basi pallidioribus ; elytris dense punctatis, pube 

 adpressa fusca vestitis, pallide fusco-violaceis. 



Long. 4 lin. 



Hab. Mysol. 



Head impressed with a longitudinal groove, which extends 

 from the anterior edge of the epistome to the vertex ; encarp;e 

 contiguous, large, pentagonal. Thorax nearly twice as broad as 

 long ; sides nearly parallel, slightly rounded in front, narrowed 

 posteriorly ; middle of disk impressed with a longitudinal sulca- 

 tion, which extends from base to apex, but is interrupted in its 

 middle ; on either side is a broad transverse depression which 

 occupies nearly a third of the whole surface ; scattered distantly 

 over the thorax, but rather more crowded on the anterior mar- 

 gin, are some large deep punctures. Elytra subparallel, lateral 

 border narrowly dilated, flattened along the suture, closely punc- 

 tured; densely clothed with adpressed fuscous pubescence; on 

 the outer disk are two shallow longitudinal sulcations, separated 

 from each other by an elevated ridge. 



Sastra limbata. 



S. elongata, pallide flava, nitida ; oculis nigris ; elytris metallico- 



violaceis, singulatim pallide flavo limbatis. 

 Long. 3| lin. 



Hab. New Guinea. 



Face short, transverse; space between the insertions of the 

 antennae broad, impressed with a longitudinal groove, which runs 

 downwards across the epistome and upwards to the vertex; ca- 

 rina: large, contiguous, subpyriform ; antennae four-fifths the 

 length of the body, slender; apex of jaws piceous. Thorax
